Answer: the maximum score was 10 feet.

Step-by-step explanation:

here's a step-by-step explanation:

Identify the minimum score: The minimum score is given in the problem as 4 feet.

Identify the range: The range is also given in the problem as 6 feet.

Calculate the maximum score: To find the maximum score, we simply need to add the minimum score and the range.

Maximum score = Minimum score + Range

Maximum score = 4 feet + 6 feet

Maximum score = 10 feet

So the maximum score was 10 feet.

The length of the corresponding sides should be equal and the length of sides is gotten using the equation:

The length of line in an ordered pair is calculated using the formula

d = √{(x₂ - x₁)² + (y₂ - y₁)²}

where

d = distance between the points

x₂ and x₁ = points in x coordinates

y₂ and y₁ = points in y coordinates

distance between points A(2, -8), B(-5, -2), C(-7, 3); and ΔDEF: D(-9, 7), E(-11, 12), F(-2, 1) are calculated as follows:

AB =√{(-2 + 5)² + (-8 + 2)²} = 6.71

DE = √{(-9 + 1)² + (7 - 12)²} = 9.43

BC = √{(-5 + 7)² + (-2 - 3)²} = 5.39

EF = √{(-11 + 2)² + (12 - 1)²} = 14.21

AC = √{(2 + 7)² + (-8 - 3)²} =  14.21

DF = √{(-9 + 2)² + (7 - 1)²} = 9.22

The correct conclusion from the given percentage of students of different categories is option(c): Classical is the preferred music for 52 students.

What is meant by percentage?

A figure or ratio stated as a fraction of 100 is called a percentage. It is frequently indicated by the percent sign, "%."

Given,

Total number of middle school students = 400

Percent of students who prefer rock = 13%

Percent of students who prefer hip hop = 25%

Percent of students who prefer pop = 35%

Percent of students who prefer classical = 13%

Percent of students who prefer jazz = 14%

Now we can find the number of students for each category.

Number of students who prefer rock = 13/100 * 400 = 52

Number of students who prefer hip hop = 0.25 * 400 = 100

Number of students who prefer pop = 0.35 * 400 = 140

Number of students who prefer classical = 0.13 * 400 = 52

Number of students who prefer jazz = 0.14 * 400 = 56

We can now look at different options.

a) This is false as hip-hop is preferred by 100 students.

b) Together Pop and jazz are preferred by 140+56 = 196, which is not more than half (200) of students. So this is false.

c)  This is true as classical is preferred by 52 students.

d) Together rock and hip hop are preferred by 52+100 = 152, which is not equal to 172. So this is false.

Therefore the correct conclusion from the given percentage of students of different categories is option(c).

Answer:

Step-by-step explanation:

Let's use the formula rate = cost/length to find the cost of one inch of wire. We know that 23 inches of wire cost 92 cents, so the rate of one inch of wire can be found by dividing 92 cents by 23 inches:

rate = cost/length = 92 cents/23 inches = 4 cents/inch

Now that we have found the rate of one inch of wire, we can use it to find the cost of 34 inches of wire. We simply multiply the rate by the length:

cost = rate * length = 4 cents/inch * 34 inches = 136 cents

So, 34 inches of wire will cost 136 cents.

Step-by-step explanation:

the trick is to find the "norm" rate, which is the rate for one unit.

from there we can get the rate for any number of units just by multiplying.

so,

23 in for 92 cents.

that means the rate is

23/92 = 23/(23×4) = 1/4

so, by dividing numerator and denominator by 23 (in this case it has an integer result also for the denominator) we get the price for 1 inch of wire : 4 cents.

so, 34 inches then have the length/price ratio (we multiply numerator and denominator by 34)

1/4 × 34/34 = 34/136

that means 34 inches cost 136 cents (= $1.36).

Trigonometric ratio in option (c) tan C will not have the same value as sin A.

Trigonometric functions are defined as the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Given a right angled triangle ABC given below.

ABC angle is 90° and angle ACB is 45°.

Then angle BAC = 180° - (90° + 45°) = 45°

Since two angles are equal, it is an isosceles triangles.

So opposite sides to the equal angles are equal.

AB = BC

AC is the hypotenuse.

Sin A = Opposite side / Hypotenuse = BC / AC

(a) Cos A = Adjacent side / Hypotenuse = AB / AC = BC / AC

(b) Sin C = AB / AC = BC / AC

(c) Tan C = Opposite side / Adjacent side = AB / BC = BC / BC = 1, not equal to Sin A

Where a is the slope and b is the y-intercept.

If a line passes through the points (x₁, y₁) and (x₂, y₂) then the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

To find the distance between the man's starting point and his final position, we can use vector addition.

Let's call the man's starting point A and his final position B. We can represent the two legs of his journey as vectors A and B, respectively.

The first leg of his journey, due west, can be represented as a vector of magnitude 4 km in the -x direction.

The second leg of his journey, on a bearing of 197°, can be represented as a vector in the -x and -y direction. We can use trigonometry to find the components of this vector.

The x component of the vector can be found using the formula:

x = magnitude * cos(angle) = d * cos(197°)

The y component of the vector can be found using the formula:

y = magnitude * sin(angle) = d * sin(197°)

where d is the magnitude of the vector (the distance the man traveled in this leg of his journey).

To find the magnitude of the vector, we'll use the Pythagorean theorem:

d^2 = x^2 + y^2

We can substitute the x and y components we found above into this equation to find d:

d^2 = (d * cos(197°))^2 + (d * sin(197°))^2

d^2 = d^2 * (cos^2(197°) + sin^2(197°))

d^2 = d^2

d = sqrt(d^2) = sqrt(d^2)

So the magnitude of the vector is d.

Next, we can add the two vectors to find the total distance from the man's starting point to his final position:

distance = sqrt((4 - d * cos(197°))^2 + (d * sin(197°))^2)

This is the distance the man is from his starting point. To find the exact value, we would need to know the value of d. However, without that information, this is as far as we can take the calculation.

The balance will be at least $1200 after 8.18 months, if you deposit $1000 in an account that pays 3.5% annual interest compounded monthly.

The result of earning interest on a principal amount as well as the accumulated interest from earlier periods is known as compound interest. It occurs when money is reinvested rather being paid out, allowing interest to be generated on the principle and accrued interest over the next month.

The balance of an account with an initial deposit of $1000 earning 3.5% annual interest compounded monthly will reach $1200 after 8.18 months.

To find the time it takes for the balance to reach $1200, we can use the formula for compound interest, A = P[tex](1 + r/n)^{nt}[/tex],

where P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

In this case, P = 1000, r = 0.035, n = 12 (because the interest is compounded monthly), and t is the unknown variable. We can rearrange the formula to solve for t:

t = (A/P) / (1 + r/n)

Plugging in the values, we get

t = (1200/1000) / (12(1 + 0.035/12))

which simplifies to

t = 8.18 months

Therefore, it will take 8.18 months for the balance of the account to reach $1200.
